Data type Range Default value
REG_DWORD 0 | 1-128 (megabytes) 0


Establishes the maximum space in the paged pool that can be allocated by any process. Any attempt by a process to allocate more space in the paged pool will fail.

Value Meaning
0 The system calculates an optimal value for this entry based on the amount of physical memory on the computer, and adjusts this value if the amount of memory changes. This value is optimal for most systems.
1–128 Overrides the value calculated by the system and prevents the system from adjusting this value dynamically. This setting can degrade performance.

Activation method

You must restart the computer before a change to this value takes effect.

Caution Image Caution

Do not change the value of this entry. The system adjusts this value dynamically based on internal algorithms. Changing this value prevents the system from calculating an optimal value. This is likely to degrade the performance of your system.
